Description

Technical Field

[0001] This utility model relates to the technical field of yarn drying equipment, and in particular to a guiding device for uniformly drying yarn packages. Background Technology

[0002] After dyeing, yarn packages need to undergo dehydration and drying. The conventional method involves placing the yarn packages in a yarn dryer and layering them on yarn rods above the yarn racks, then drying them by blowing hot air into the dryer. Because the yarn packages are layered on the yarn rods, the existing unidirectional hot air drying method results in varying degrees of drying due to heat distribution on yarn packages at different heights and in the inner or outer layers, leading to uneven drying results within the same batch of yarn packages. Utility Model Content

[0003] The purpose of this invention is to provide a guiding device that ensures uniform drying of yarn packages. By combining the first and second tubes, a switchable airflow path is formed. The direction of the hot air flow can be changed by using a reversing guide vane. The overall structure is simple and solves the problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A guiding device for uniformly drying yarn packages includes a base with an upward-opening cavity. A first tube and a second tube are vertically connected inside the base. The first tube has a hot air inlet and a hot air outlet extending to the outside of the base, respectively. The lower part of the second tube communicates with the upper middle part of the first tube. The upper part of the second tube has a first outlet. A second outlet, annularly distributed around the first outlet and communicating with the cavity, is formed between the first outlet and the upper part of the base. A third outlet, communicating with the cavity, is opened on the lower middle part of the first tube. A deflector plate is rotatably connected to the middle of the first tube. The base is connected to a driving device for driving the deflector plate to rotate toward the first or third outlet to change the airflow direction.

[0006] Furthermore, the driving device includes a drive shaft rotatably connected to the seat body, the middle part of the reversing air guide plate is connected to the drive shaft, and one end of the drive shaft has a driving end.

[0007] Furthermore, the drive shaft has an assembly hole for inserting the reversing air guide plate, and the middle part of the reversing air guide plate is connected to the drive shaft by a fastener.

[0008] Furthermore, the first outlet is equipped with a grid.

[0009] Furthermore, the first outlet is provided with a first wind deflector located above the grid, and a support member is connected between the first wind deflector and the first outlet, forming a ventilation channel between the first wind deflector and the edge of the first outlet.

[0010] Furthermore, the first wind deflector has ventilation holes.

[0011] Furthermore, the second outlet is equipped with a ring-shaped mesh cover.

[0012] Furthermore, the upper end of the second tube is higher than the upper end of the base, and the mesh cover is frustoconical.

[0013] Furthermore, the second outlet is provided with a second wind deflector that bends outward.

[0014] Furthermore, the bottom of the seat is provided with a drain pipe that communicates with the cavity.

[0015] Compared with the prior art, this utility model provides a guiding device for uniformly drying yarn packages, which has the following beneficial effects:

[0028] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] Please refer to Figures 1-9This embodiment provides a guiding device for uniformly drying packaged yarn 10, including a base 1. The base 1 has an upward-opening cavity 11. Inside the base 1, a first tube 2 and a second tube 3 are vertically connected. The two ends of the first tube 2 are respectively provided with a hot air inlet 21 and a hot air outlet 22 extending to the outside of the base 1. The lower part of the second tube 3 is connected to the upper middle part of the first tube 2, and the upper part of the second tube 3 has a first outlet 31. The first opening can be used to connect with the bottom of the yarn rack 8 inside the packaged yarn dryer 7. The first tube 2 has an opening that connects to the upper part of the base 1. A second outlet 12 is formed in a ring around the outer periphery of the first outlet 31 and is connected to the cavity 11. The second opening can be used to connect to the bottom of the inner cavity of the yarn dryer 7. A third outlet 23 connected to the cavity 11 is opened on the lower side of the middle part of the first tube 2. A deflector plate 4 is rotatably connected to the middle part of the first tube 2. The base 1 is connected to a drive device 5 for driving the deflector plate 4 to rotate toward the first outlet 31 or the third outlet 23 to change the airflow direction. By setting a first tube 2 and a second tube 3 inside the base 1, the first tube 2 is used to input and discharge hot air, and the first outlet 31 on the second tube 3 and the second outlet 12 on the base 1 are used to direct the hot air to the yarn package dryer 7 or backflow. The cooperation of the first tube 2 and the second tube 3 forms a switchable airflow path, and the guide vane 4 is used to change the direction of the hot air flow. The overall structure is simple and can keep the drying uniformity of each yarn package 10 distributed in the upper and lower layers and the inner and outer layers within the standard deviation range (i.e., a difference of 45~60g), avoiding yellowing during the drying process.

[0030] In some embodiments, reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The drive unit 5 includes a drive shaft 51 rotatably connected to the base 1 via a bearing housing 52. The middle part of the reversing air guide plate 4 is connected to the drive shaft 51. One end of the drive shaft 51 has a drive end 511 for connecting to an external power device. When an external power device acts on the drive end 511, it drives the drive shaft 51 to rotate, thereby driving the reversing air guide plate 4 to rotate, thus realizing airflow reversal.

[0031] As an example, the external power device can be a drive that provides rotational power, such as an electric motor or a pneumatic motor.

[0032] like Figure 6 As shown, in an improved embodiment, to facilitate quick assembly and disassembly of the replacement air guide plate 4, the drive shaft 51 has an assembly hole 512 for inserting the replacement air guide plate 4. The middle part of the replacement air guide plate 4 is connected to the drive shaft 51 via a fastener 53. In this way, the replacement air guide plate 4 can be quickly assembled with the drive shaft 51 using the fastener 53, and because it is detachable, it is also convenient for subsequent maintenance.

[0033] As an example, fastener 53 is a bolt and nut assembly.

[0034] In some embodiments, reference Figures 1-9 The first outlet 31 is equipped with a grid 32 to prevent foreign objects from falling into the second tube 3.

[0035] As an improved embodiment, such as Figure 4 As shown, the first outlet 31 is provided with a first baffle plate 33 located above the grid 32. A support member 34 connects the first baffle plate 33 and the first outlet 31, and a ventilation channel is formed between the first baffle plate 33 and the edge of the first outlet 31. By adding the first baffle plate 33, excessive airflow can be prevented from causing the yarn package 10 near the first outlet 31 to become too dry. In addition, since the ventilation channel is distributed in a ring shape between the first baffle plate 33 and the edge of the first outlet 31, the airflow has a diversion effect when flowing through the first outlet 31.

[0036] As an example, the first wind deflector 33 is a circular metal plate.

[0037] In some embodiments, such as Figure 4 As shown, the first baffle plate 33 has ventilation holes 331. In this way, some hot air can pass directly through the ventilation channel, while the rest of the hot air passes through the ventilation holes 331, creating a diversion effect.

[0038] As an example, the ventilation hole 331 can be a plurality of small round holes evenly distributed in the middle of the first wind deflector 33, or it can be a large round hole in the middle of the first wind deflector 33.

[0039] In some embodiments, reference Figures 1-9 The second outlet 12 is equipped with a ring-shaped mesh cover 13 to prevent foreign objects from falling into the interior of the seat 1.

[0040] Preferred, such as Figure 1 and Figure 3 As shown, the upper end of the second tube 3 is higher than the upper end of the base 1, and the mesh cover 13 is truncated cone-shaped. This can increase the efficiency of hot air passage and facilitate the rapid circulation of hot air.

[0041] As an improved embodiment, such as Figure 7 As shown, the second outlet 12 is provided with a second baffle plate 6 that bends outward. Thus, when the hot air is controlled to pass through the yarn package 10 for drying in an outward manner, the hot air is guided by the second baffle plate 6 during its entry into the yarn package dryer 7 from the base 1, changing the airflow direction and forming a local vortex airflow that diffuses outward. This ensures that the yarn packages 10 located on the outer layer also receive uniform hot air, guaranteeing consistent drying results.

[0042] As an example, the second wind deflector 6 is a metal plate with an L-shaped cross-section.

[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the bottom of the base 1 is provided with a drain pipe 14 that communicates with the cavity 11. By adding the drain pipe 14, the softener and other liquids that fall and remain at the bottom of the yarn dryer 7 can be drained, solving the problem of liquid residue.

[0044] As an example, the outlet of the drain pipe 14, as well as the hot air inlet 21 and the hot air outlet 22, are provided with flanges for easy sealing connection.

[0045] refer to Figure 8 and Figure 9 During installation, the guide device is installed at the bottom of the yarn package dryer 7. The first opening is connected to the bottom opening of the yarn rack 8 inside the yarn package dryer 7, and the second opening is connected to the bottom of the yarn package dryer 7. The hot air inlet 21 is connected to the air outlet of the fan through a pipe, and the air inlet of the fan is connected to the heat exchanger used for heating the air through a pipe. The hot air outlet 22 is connected to the cooler with a steam-water separator through a pipe, and the cooler is connected to the heat exchanger through a pipe.

[0046] like Figure 8 As shown, during the drying process, the fan, as the power source providing air pressure and volume, draws high-pressure air heated by the heat exchanger into the guide device via the hot air inlet 21. Then, guided by the reversing guide vane 4 (e.g., rotating counterclockwise at a preset angle to connect the hot air inlet 21 with the first outlet 31 and the third outlet 23 with the hot air outlet 22), the air is discharged upwards through the first outlet 31 into the yarn rack tray 8. Subsequently, the yarn rods 9 on the yarn rack tray 8 pass through the yarn package 10 from the inside out and enter the inner cavity of the yarn package dryer 7, carrying away the moisture inside the yarn package 10. The hot air containing moisture enters the cavity 11 of the base 1 through the second outlet 12, and then passes through the third outlet 23 and the hot air outlet 22 in sequence to the cooler to condense and separate the moisture, obtaining dry air that flows back to the heat exchanger for reheating. This continuous cycle removes moisture from the yarn package 10 and achieves the drying purpose.

[0047] During this period, such as Figure 9As shown, in order to improve drying efficiency and drying effect, the flow direction of hot air inside the yarn package dryer 7 is changed by controlling the rotation of the reversing guide plate 4. Specifically, the reversing guide plate 4 is driven to rotate clockwise by a preset angle, so that the hot air inlet 21 is connected to the third outlet 23 and the first outlet 31 is connected to the hot air outlet 22. In this way, the heated high-pressure air is input into the guide device through the hot air inlet 21, and then discharged downward through the third outlet 23 into the cavity 11 of the base 1 under the guidance of the reversing guide plate 4. After that, it enters the inner cavity of the yarn package dryer 7 from the second outlet 12, passes through the yarn package 10 from the outside to the inside and takes away the moisture inside the yarn package 10. The hot air containing moisture enters the yarn frame plate 8 through each yarn rod 9 and is discharged through the first outlet 31 and the hot air outlet 22 in sequence, completing the hot air reversing drying. After multiple reversing drying processes, the yarn package 10 is dried evenly.

[0048] The above embodiments are merely illustrative of the concept and technical solution of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
